Prior to the beginning of the 21st century, the majority of cars utilized basic key systems. Keys were made from metal and incorporated grooves to correspond with the internal parts of the ignition cylinder. As technology advanced the number of car makers began to combine electronic and physical protocols to avoid theft. Key systems like these are also referred to as transponder keys or chips keys are designed to make it difficult for thieves to start the vehicle.

The key chips come with unique serial codes that transmits a message to the receiver in your car. The signal is compared with the computer of the car when it is received. If the codes match then your car will start. If the codes don't match, then your car won't even start. This is why you should keep a spare car key, particularly if your system is based on transponders.

You'll require special equipment to learn how to program keys. You'll also need the blank key that matches your specific make and model. You can buy them at an auto locksmith or a locksmith dealership, but it's important to purchase the correct keys. If you try to use a key that is from another model, then it won't work.

Start the process by inserting the new key in the ignition and turning it "on". You'll need to keep the key in this position for around 10 minutes and 30 seconds. Once the time has expired you can take out your key and verify that the security indicator on your dashboard has gone off. If not, you'll need to do it again for a third time.

This method is only compatible with GM vehicles and isn't completely secure. If you're seeking a more secure and reliable option, you should seek out a professional locksmith or the dealer to have your car programmed with chips. They have the tools and equipment needed to access the onboard diagnostic port of your car and make the switch.

Keyless Entry Systems

Keyless entry systems grant access to properties without the requirement of a physical ID. Security is offered by a combination between sensors and an onboard computing device. It is possible to monitor and control the system from anywhere within the property. Keys and locks are not required. The system can also detect and block stolen or lost cards. The latest models also support remote management and configuration and are cloud-based.

Most modern cars are equipped with a keyless entry system. To enable this feature the car key programing emits radio signals that are detected by a particular key fob. The signals are then compared against the correct code that is stored in the car's system, and when everything is in order the car will be able to unlock. The car will not start if the signals are not the same. If your key fob has not been already programmed, you can follow a series of steps to programme it.

Transponder Keys

Transponder keys, sometimes referred to as chip keys, have a microchip built into the head of the key. When the key is inserted into the barrel of the ignition lock and then turned to ON, the antenna ring sends a burst of electromagnetic energy through the transponder chip. The energy is absorbed by the chip and sends back an audio frequency signal that contains an identification code that matches with the unique serial number that is stored in the car's computer system. This stops unauthorised attempts to start the car since only proper keys will be able to do so.

It is believed that this technology will be more secure than traditional keys for cars because it makes it much difficult for thieves to "hot wire" a vehicle and start it. It's not foolproof, and thieves have discovered ways of tricking and defeating the system. So even cars with transponder keys aren't protected from theft.

You could be able to program a transponder key on your own with an instrument that works with your car. The key programmer will come with a step-by-step guide that will walk you through the process of programming your key.

The key fobs have electronic chips that communicate using radio signals with the car's receiver. The car's computer then compares the key's code to the one in its database. If the codes match the car will begin. If not, the vehicle will not start or fail to start.
